Brandon, these have enough oomph to cycle most semi-auto's as the slug loads are still hotter than low recoil buckshot loads. Cheers and stay safe!

Brandon, These should cycle in a semi auto shotgun, but you never know. Buy a box and check them out. Don't buy a case full until you have checked out how the function in your shotgun.

it will be fine in most semi autos it may have problems in some of the 3 and 3.5 inch chambered guns the only way to know for sure is to try them
